Research to better understand the influence of indoor and outdoor air quality on the health of Canadians

Health Canada

Current research and/or projects

Health effects of exposure to indoor chemicals and outdoor air pollutants.

Research and/or project statements

We have found evidence based mostly on observational studies suggesting that:

Indoor exposure to selected VOCs and phthalates may impair lung function.

Exposure to outdoor air pollution is associated with impaired lung function, selected cardiac rhythm disorders, deep venous thrombosis, epilepsy,hospitalization, and mortality.

The elderly and socially disadvantaged may be more susceptible to the adverse effects of outdoor air pollution 

Environmental health studies help to assess the burden of illness due to air pollution which is needs to be taken into consideration by regulators.
